Abstract (en)

[origin: EP3401828A1] To achieve high-speed and efficient parameter calculation processing of a logistic regression model. A logistic regression parameter is calculated, the logistic regression parameter being a parameter of the logistic regression model indicating the relationship between an explanatory variable and an outcome variable being secure data corresponding to each sample. A data processing unit calculates the inner product (t_s) of the explanatory variable and the outcome variable with application of secure computation being computation processing applied with converted data of each of the variables, and performs computation processing excluding the calculation processing of the inner product, as computation processing without the converted data, to calculate the logistic regression parameter in accordance with the maximum likelihood method with the Newton-Raphson method (iterative convergence method).
